MAN Energy Solutions on Wednesday (29 March) said MAN 49/60DF engine has received its Type Approval after a five-day programme on the testbed at company HQ in Augsburg, Germany.

The Type Approval Test (TAT) was witnessed by inspectors representing the ABS, BV, CCS, DNV, LR and RINA classification societies, who signed the test protocol upon the successful completion of the schedule.

Marita Krems, Head of Four-Stroke Marine & License, MAN Energy Solutions, said: “Today marks the latest milestone in the 49/60DF’s journey since its concept release in 2018. As we enter a new era of decarbonisation, the 49/60DF is an obvious choice for vessel owners with ambitious, emission-reduction targets that prize full fuel-flexibility and multiple options for clear emission paths.”

Thomas Huchatz, Sales Manager Four-Stroke Marine, MAN Energy Solutions, said: “Over the last eighteen months, we have demonstrated the engine’s reliability and robustness. The TAT now issued is a certificate of conformity that confirms that the engine meets the regulatory, technical and safety requirements required to enter the marketplace.”

The most recent addition to its four-stroke engine portfolio, the dual-fuel engine is capable of running on LNG, diesel and HFO as well as a number of more sustainable fuels including biofuel blends and synthetic natural gas. MAN Energy Solutions states that it sets a benchmark in terms of fuel efficiency within four-stroke engines – both in gas and diesel mode – and therefore minimises fuel costs and potential costs for CO2-emission certificates.

The new 49/60DF engine platform features MAN’s latest technologies, including two-stage turbocharging, second-generation common-rail fuel injection, the SaCoS5000 automation system, and MAN’s next-generation Adaptive Combustion Control ACC 2.0 that automatically optimises combustion. The engine also retains well-proven MAN technolgies such as the gas-injection system, pilot-fuel-oil system and MAN SCR (Selective Catalytic Reduction) system.

The MAN 49/60DF can operate and even start in gas mode where it complies with IMO Tier III without exhaust gas after-treatment. In diesel mode, it complies with Tier III when combined with MAN’s SCR system.

Soot emissions in diesel mode are halved due to the second-generation common-rail system 2.2, while the 49/60DF’s methane emissions are also drastically reduced in gas mode. The engine’s benchmark efficiency and fuel-flexible design offers multiple paths to emission compliancy leading up to 2050, as per the current Fuel EU draft.

The new engine is also methanol-ready, meaning it is inherently ready for retrofit to running on methanol should the demand arise at a later stage. Conversions are straightforward as all engine variants originate from an initial, modular engine design.

MAN Energy Solutions is also introducing a pure diesel engine based on the 49/60 platform that will be methanol- and LNG-ready and features the same technology upgrades as its dual-fuel sibling; the engine can also operate on bio-fuels.

Tsuneishi delivers world’s first methanol dual-fuel Ultramax bulker to NYK

Tsuneishi Shipbuilding on Wednesday (14 May) said it has delivered the world’s first methanol dual-fuel Ultramax bulk carrier, Green Future.

The 65,700 dwt vessel was delivered at its factory on 13 May and will be chartered by NYK Bulk & Projects Carriers, an NYK Group company, from Kambara Kisen.

Tsuneishi Shipbuilding said the vessel maintains the high cargo capacity and fuel efficiency characteristic of the TESS66 Aeroline design series, while enabling more sustainable operations through the use of methanol as a fuel.

The methanol fuel tank has been positioned to maximise safety and facilitate smooth cargo handling while maintaining loading efficiency. It is also equipped with a fuel-efficient main engine and Tsuneishi’s proprietary Aeroline technology to reduce wind resistance, delivering superior fuel performance.

Mr Okumura Sachio, Representative Director, President & Executive Officer of Tsuneishi Shipbuilding, said: “This delivery marks just the beginning. We will continue constructing methanol dual-fuelled vessels at our overseas facilities and remain steadfast in our pursuit of technological innovation to contribute to a more sustainable maritime industry and global environment.”

NYK said the vessel is the first bulk carrier in the NYK Group to be equipped with a dual-fuel engine that uses methanol and fuel oil.

Burando Energies completes B30 bunkering operation for Teekay Tankers

European marine fuel supplier Burando Energies on Wednesday (14 May) said it has successfully completed a bunkering operation for Teekay Tankers, delivering a bespoke blend of Very Low Sulphur Fuel Oil (VLSFO) containing 30% ISCC Certified FAME Residue in the Port of Amsterdam.

By blending its VLSFO with FAME Residue, Burando Energies said it is able to provide a scalable solution that meets both commercial and environmental targets.

“We are proud to support Teekay Tankers in taking concrete steps toward sustainable operations,” said Nick de Haan, Head of Decarbonisation Strategies at Burando Energies.

“This delivery showcases our ability to meet the evolving fuel demands of the global shipping industry with innovative, lower-carbon solutions that are also commercially viable.”

FAME (Fatty Acid Methyl Esters) Residue is a renewable, second-generation bio-component derived from waste oils and residual feedstocks from biodiesel production. Unlike conventional biodiesel, FAME Residue is considered a more economical and circular option, offering a reduced carbon footprint at a lower cost.

Through extensive testing and evaluation, Burando Energies has secured a consistent, FAME Residue stream that blends well with VLSFO and maintains full compatibility with existing marine engines. The result is a drop-in fuel blend that lowers lifecycle emissions while enhancing both operational efficiency and fuel flexibility.

“Teekay Tankers has partnered with Burando for many years and has worked with us on the first FAME Residue biofuel delivery in Amsterdam,” said Mads Bjornebye, Manager Bunker Services at Teekay Tankers.

“Burando coordinated closely with both our Technical and Commercial teams to ensure a smooth delivery.”
